    A genome-wide scan of positive selection signature using Ovine Infinium® HD SNP BeadChip in two Romney lines, selected for resistance or resilience to nematodes
    (3/07/2017) Yan J; Dukkipati VSR; Blair HT; Biggs PJ; Hamie JC; Greer A
    A study was undertaken to identify selection signatures associated with resistance to gastrointestinal nematodiasis in sheep. Ninety-three Romney sheep from two selection lines (resistant or resilient) were genotyped using the Ovine Infinium® HD SNP BeadChip, and extended haplotype homozygosity (EHH) and site-specific extended haplotype homozygosity (EHHS) analyses were undertaken. In total, 224 SNPs (147 in EHH and 77 in EHHS) were found to be significant (p <0.0001). Preliminary exploration of 10 SNPs found them to be located within two previously identified QTLs, namely LATRICH_2 and FECGEN, which were associated with nematode larval count and faecal egg count, respectively.

    Characterising the drinking water microbiome on campgrounds in New Zealand
    (23/10/2012) Phiri BJ; Biggs PJ; Prattley DJ; Stevenson MA; Rainey PB; French NP
    Whole-genome, 16S and 18S ribosomal RNA (rRNA) analyses combined with conventional isolation techniques are being applied to profile microbial community DNA associated with drinking water on campgrounds. The current study has a serial cross-sectional design and is being conducted on 15 campgrounds that are situated across New Zealand (Figure 1) and are managed by the Department of Conservation (DOC). Preliminary results generally show low Escherichia coli counts in water, suggesting minimal faecal contamination, and a low proportion of faecal samples were positive for Campylobacter and Giardia.
